150mA Ultra Low Supply Current
LDO REGULATOR
RP104 SERIES
NO.EA-150-070712
OUTLINE
The RP104 Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low
supply current and low ON-resistance. Each of these ICs consists of a voltage reference unit, an error amplifier,
resistor-net for voltage setting, a current limit circuit and a chip enable circuit.
These ICs perform with ultra low supply current (Typ.1.0µA), which prolong the battery life.
Since the packages for these ICs are PLP1010-4, SOT-23-5 and SC-82AB, therefore high density mounting of
the ICs on boards is possible.
